SPECIFICATION forming part of Letters Patent No. 559,808, dated May 12,1896*.

Application iled January 14, 1896. Serial No. 575,425. (No model.)

To all whom, t 11i/ay concern.-

Be it known that I, THOMAS FRANCIS MUR- PHY, a citizen of the UnitedStates, and a resident of New York, in the county of New York and Stateof New York, have invented certain new and useful Improvements inlVindow-Fasteners, of which the following is a Specification, referencebeing had to the accompanyi ng drawings, forming a part thereof, inwhich similar letters of reference indicate corresponding parts.

This invention relates to locks for windowsashes, and the object thereofis to provide an improved device of this class which consists of twoparts, one of which is adapted to be connected with the upper part ofthe frame ot the lower sash and the other to the lower part of the frameof the upper sash, and that part which is connected with the lower sashheilig provided with a spring-operated bolt which operates in connectionwith the part which is connected with the upper sash, so as to securelylock said sashes together; and with this and other objects in view theinvention consists in the construction, combination, and arrangement ofparts hereinafter described and claimed.

The invention is tull5T disclosed in the following specification, ofwhich the accompanying' drawings form a part, in which-- Figure 1 is aplan view of my improved sash-lock, showing the saine connected with theupper and lower sashes and in operative position; and Fig. 2, a sectionon the line 2 2.

' In the drawings forming' part of this application, A represents thebottom portion of the f rame of the upper sash, and B the upper part ofthe .frame of the lower sash, and in the practice of my invention Iprovide a sashlocl: comprising a plate O, which is adapted to be securedto the frame of the lower sash, and a plate D, which is adapted to besecured to the frame of the upper sash.

The plate D has a vertical curved or segmental shoulder or projection dformed thereon, in the outer side of which is formed a hole or openingd2, (shown in dotted lines in Figs. l and 2,) and pivotally connectedwith the plate O is a swinging arm Gr, which is provided near itscentral portion with an upwardlydirected shoulder g, and the free end ofwhich is provided with a curved or segmental head 4said hole or openingby said Spring.

g2, and passing through the shoulder G and the curved or segmental headg2 is a sliding spring-operating bolt ll, which is provided inside ofthe shoulder gwith a pin h, and mounted on said sliding bolt, between.the shoulder g and the segmental head g2, is a spiral spring K, one endot which bears upon the shoulder g and the other or outer end of whichis secured to the sliding bolt- The operation will be readily understoodfrom the foregoing description, when taken in connection with theaccompanying drawings. lVhen itis desired to lock the upper and thelower sashes together, it is onlynccessary to take hold of the pivotedarm ll and to swing it into the position shown in Fig. l. In thisoperation the sliding bolt ll is driven backward when it strikes theshoulder d. on the plate D, against the operation of the spring K, untilthe end thereot` reaches the hole or opening d2, when it is projectedinto ln this position of the parts it will be apparent that the upper and lower sashes will be securely)v locked together, and they will be heldin this position until the sliding bolt ll is withdrawn from itsconnection with the plate D or the shoulder d, formed thereon, which maybe done by pulling outwardly on the bolt H or the pi n 7L, when the armG may be again turned to one side, after which the sashes may be raisedand lowered as desired.

My improved sash-lock also prevents the sashes from rattling, the forniof the segmental head g2 acting as a cam in connection with the shouldercl of the plate D to produce this result, and in this ope ration itisalso aided by the spring K, which may be so arranged as to force thebolt into the shoulder or projection CZ ou the plate D with such forceas to prevent the rattling of the sashes, but it will be apparent thatthe sliding bolt and the spring mounted thereon may be so arranged as toproduce this result alone.

My invention is not limited to the exact forni, construction, andarrangement of parts hereinbefore described, and itis evident thatchanges therein and modifications thereof may be made without departingfrom the spirit of my invention or sacriiicing its advantages.

Having fully described my invention, I

lOO

claim as new and desire to secure by Letters Patent- A sashlock forwindows comprising a plate which is adapted to be secured to the lowersash, an arm pivotally connected therewith, a sliding` spring-operatedbolt connected with said arm and a plate adapted to be secured to theupper sash, and provided with a hole or opening into which said bolt isadapted to be projected, said arm being' provided at its outer end witha curved or segmental head and with an upwardly-directed shoulderthrough which the bolt passes, and said bolt being also provided with aspiral spring which is mounted thereon between said shoulder and saidhead, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed mynaine, in presenee of the subscribing` WitnessesJ this 13th day ofJanuary, 1896.
